EAST RUTHERFORD, N.J. — Reports say New York Giants safety Will Hill is facing a possible third suspension for violating the NFL's substance abuse policy.

Hill could face a suspension of six games to a year depending on what the tests showed.

Hill was suspended for the first four games of the 2012 season for using a performance-enhancing drug, which he said was Adderall. He was suspended for the first four games last season for using marijuana, which he said was to relieve stress. He underwent drug rehabilitation in March and April in Boston last year, and followed up that with outpatient meetings in New Jersey.
